Application led November 14, 1913. A Serial No. 801,001.

To all whom it may concern Be it known that I, FREDRICK S. DioxinsoN, a citizenof the United States, and resident of New York, in the county and State of-New York, have invented certain new and useful Improvements in Looms, of whichthe following is a specification.; V

This invention relates to looms, and it has special relation to an improved loom mechanismfor weaving a tubular endless fabric adapted to be employed as the body fabric in the carcass or casing .of pneumatic wheel tires for automobiles or the like.

The object of my invention is to provide an improved loom which will be adapted to effectively weave a tubular endless fabric shape as to conform .to the normal contour of the tire, without stretching, pulling, packing, or otherwise distorting the weave, thus maintaining a uniform tension on each and every strand of both warp and woof threads throughout the body of the completed fabric, and thereby retaining the initial strength of every strand in the woven mass.

A further object of my invention is to provide an improved loom mechanism for producing a" fabric, such as that -just described, either in single or multiple plies,

with the multiple plies either interwoven in a unitary homogeneous fabric or woven in ,separate relationship. l

A further object of my invention is to provide a simple and improved loomlmechanism, which will in its leading features be adapted for effective Weaving under usual or `general conditions, which will be positive and convenient in operation, and which will furthermore possess advantages in point of adaptability to various forms of weaving, effectiveness, and general efficiency.

Corresponding parts in all the figures are denoted by the same reference characters.

Referring to lthe drawings, 1 designates an upright framework arranged to carry all the operating parts of the loom mechanism. From said framework extends a laterallyprojecting fixed shaft, 2,v upon the outer end of which isrevolubly mounted a reel', 3, which in its igeneral structure is of wheel form and is constituted by a Series of radial spokes, 4., as will bel hereinafter described. The hub, 5, of the reel 3 is keyed, as at 6, to the extendedhub, v7, of a gear wheel, 8, revolubly mounted upon the shaft, 2, and said gear 8 meshes with a pinion, 9, carried by a revoluble vstud shaft, 10, havingv its bearing, as at 11, inthe framework 1. Said pinion is fixed to a ratchet wheel, 12, which is actuated by a pawl, 14, carried Iby a rocking lever,` 15, loosely mounted upon the shaft 10, and said lever is actuated by a yoke or connecting rod, 16, carrying at its outer end a roller, 17, coperating' with the periphery of a cam disk, 18, carried by a driving shaft, 19, having its bearing, as at 20, upon the framework 1, said.driving shaft passing through a guide slot, 21, in the outer end of'the yoke 16. Said driving shaft 19 suitably carries 'band wheels or 'pul1eys,'as'

tion, 23, of said spokes being `normally maintained in extended outward position with relation to the main socket or base section, 24, by compression springs, 25, carried by said socket section. The projecting section or member 23 of the spokes carriesv the means for carrying the warp prior to the weaving of the woof` and the means for supporting the fabric after the weaving of the Woof. Such first mentioned means, as

herein shown, 'consists of a ring, 26, of arc shape 1n cross section, which 1s pivotally mounted,- as at27, upon the outer end4 ofthe spoke section 23 and is provided at its periphery with a series of projecting guide pins, 28, for retaining the threading of the warp in position as it is carried by the reel prior to the -Weaving of the Woof. The

. spread ofsaid arc rings 26 is preferably greater than the diameter of the tubular fabric as woven, sothat in their approach to the position for the Weaving of the Woof the warp threads are spread in the manner -indicated in Fig. 3.

` It will be understood that the number of vrpins or teeth 28 forming the comb for holding the Warp threads is 4regulated by the 4number of warp` threads it is 'desired to employ, and that the Warp4 is initially Wound between said teeth and around the entire reel in a continuous length, the relative size of the arc rings 26 and their teeth 28 being such that the proper circumference and position is .given to each thread section of the warp to form the required shape and sizeofthe endless tubular fabric it is desiredto Weave, due allowance being made for the take up in the weaving of the Woof and for compensating for the percent-` age of crimp it is desired to put in the warp.

A circular ring, 29, in band form, is also pivotally mounted, as at 30,.uponthe outer end of the spoke sections 23, the office ofv which ring is to support and carry the fabric after the weaving of the Woof. Said rings29have vtheir pivot intermediate of the pivotal Amounting of the arc rings 26, and are therefore adapted to swing within the latter, as more clearly shown in Fig. 9, and said rings 29 are adapted in size to the shape andvcross section of the inner diameter of the woven tubular endless fabric.- .Y -fi The rings 26 and 29 are pivotally 'mounted in transverse relation to the axis of the reel, and constitute the peripheral portion thereof by which the Warp and also the woven fabric are carriedl during the revoluble step movement of the reel. In said latter movement, it is necessary that the Warp be freed from said carrying means during the weaving of the Woof and. tjlejfjyaction of the heddles, and it is thereforl'iiecessary to .trip said warp-carrying means from operative position prior to the Weaving of the Woof, vand also to afterward bring the rings 29 into operative position for supporting the fabric after the weaving of the woof. In the preferred construction for said tripping action, the arc rings 26 are provided with a projecting lug, 31,'and the circular rings 29 are also provided with a projecting lug, 32, these lugs being arranged in fulcrum position with relation to the pivots of therings and being adapted to be simultaneously engaged by projecting trip lugs, 33 and 34, respectively, carried upon a movable trip member, 35. The trip lugs 33 and 34 are brought into action, during the movement of the reel, at a point a suitable distance in advance of theshuttle mechanism, to throw the rings 26 and 29 upon their pivots and permit their movement to the position as shown in' Fig. l, to remove the arc ring from .the warp before the warp moves upto theshuttle mechanism. The carrying member 35 for the trip lugs 33 and 34 is slidably mounted in a bearing, as at 36,at the projecting end o f a lever, 37, pivotally mounted, as at 38, upon the framework 1, and beyond said sliding bearing the member 35 has its end pivoted, as at 39, to the projecting end of another lever, 40, arranged at right angles to the lever 37 and having its fulcrum, as at 41, upon said lever 37 (see Fig. 4). Said lever 37 carries, at a point adjacent the fulcrum of the lever 40, a roller, 42, bearing against the edge of a crown cam wheel, 43, mounted at right angles to the pivotal movement of the lever` 37 and fixed to the revoluble shaft 10 which .is actuated by the pawl and ratchet mechanism hereinbefore described in connection with the driving means for thereel.3. rIhe roller 42 'is held in yielding engagement with relation to the cam 43 by a suitably mounted spring, 44, exerting its4 tension when the trip member-35 is projecting in its .slidable bearing, and'to effect ythis n'fiovement'rthe free end of the lever 40 is provided with a roller, 46, adapted to engage the edge of a cani,47, mounted in parallel relation te the cam 43 and upon the driving shaft 19, whereby when the lever is carried outwardly by the movement of the lever 37 it will be actuated by the cam 47 to move the trip member 35 in its slidable bearing and bring the lugs 33 and 34 in engagement with the lugs 31 and 32, and thus trip the rings 26 and 29 and permit them to move to the position shown in Fig. 1 to disengage the arc ring 26 from the warp. After theaction just described, the lever 37 returns to normal position (see Fig. 4), by further movement of the cam wheel 43, and thus carries the lever 40 to normal'position with its roller.

46 beyond the plane of engagement with cam 47, which movement ieturns the trip lugs 33 and 34 to their normal position, as shown in full lines in Fig. 4, out of the path of.

movement of the succeeding spokes 4 of the reel 3. After the rings 26 and 29 are tripped under the operative action just described, and while the spokes of the reel are passing in their path of movement beneath the shuttle mechanism, a roller, 48, mounted at one side of the projective spoke section 23, enters into engagement with a cam track, 49, suitably mounted upon the framework 1 and having an irregular curvature whereby as said' roller 48v travels in engagement with said cam track they spoke section 23 is telcscoped Withiriithe socket or base spoke section 24 until the terminus of thecam track is reached at a point beyond thelocation of the shuttle mechanism, when the spoke' section 23 returns to outward normal projective position by action of spoke spring 25 (see Figs. 1 and 2). The outer ring portions 26 and 29 of the spokes are thus, after they are ltripped from engagement with the warp,

.-,pin 5 1, projecting laterally held down away from the shuttle mechanism, during the passage of the spoke beneath the latter, and the ring 29 is then returned to outward position at a point a distance beyond thelocation of the short shuttle mechanism. The downward position of the ring portions 26 and 29 is limited by the engagement of a lug, 50, with a stop from the spoke section 23, as shown in Figs. 1 and9.

The return of the ring 29 to outward posi'- tion, after it has passed beyond the location of the shuttle mechanism, is effected a latch mechanism which engages said ring and returns yit to upward position in a radial plane with relation to the spoke, thus bringing the ring within the woven fabric after the latterfhas 'passed beyond the shuttle mechanism, in'which'position said ring will support the woven fabric upon the reel during the further step movement thereof, as illustratedin `Fig. 1.v In the preferred construction, the latch mechanism for this purpose comprises a pivoted catch, 52, adapted crum, as at 53, upon a block, 54, slidably. mounted on a rod or arm, 55, the pivotal movement of the catch being governed by a spring, 56, and a stop-pin, 57, respectively carried by the block 54. Said sliding block 7-0 carries a projecting pin, 58, having a bearing 4in a slot, 59, at' the end portion of one arm of a bell-crank lever, 60, which is suitably fulcrumed upon the framework, and has its other arm pivotally connected with a link or 75v connecting rod, 61, which at its other end is pivoted to anotherbell-crank lever, 62, suitably fulcrumed upon the framework. Said latter lever is pivotally. connected with a yoke bar, 63, slotted to provide a sliding sa bearing upon a shaft, 64, suitably journaled in the framework, and carrying a roller, 65, engaging the periphery of a cam disk, 66, carried by said shaft 64. Thus, by operation of the cam 66 andthe connections as above 'a5 described, the bell-crank lever 60 is actuated to slidably move the block 54 upon its guide rod 55 and thus cause Vthe operative action of the catch 52 to throw the ring 29 into position to support the woven fabric. The 9o latch mechanism also/has a lateral movement so that the sliding block 54 carrying the catch 52 and the rod or arm 55 Will be intermittently operated to bring the same to a position in whichit will clear the spokes 4 95 of the reel 3 during the revoluble movement of the latter. The preferred mechanism for this purpose comprises a lever, 67, carrying therod or arm 55 and suitably fulcrumed upon the framework 1, said lever carrying at its free end a roller,

68, engaging with a lateral projection, 69, on the cam wheel 43'` of the tripping mechanism by which the rings 26 and 29 are brought to downward position from engagement with the Warp as hereinbefore described. Thus, by action of the cam wheel 43, the lever 67 is operated in a lateral movement to move the latch mecha-e nism out ofthe path of the spokes of the reel` Y 3 'and to return the same to operative posi- 11C tion, the movement being suitably timed with relation to the operative action of the other parts of the general mechanism. The lever 67 is of suitable angular contour to properly span in operative position. the 11F lspace between the rod or arm 55 and the actuating' cam wheel 43. A brake band, 70, is preferablyy suitably arranged with relation to the extended hub- 7 of the gear wheel 8 by'which the reel 3 12o is driven, to effect proper tension with relaf tion to the movement of the warp under the reel action and to prevent 'the vgear 8 and the reel mechanism which it drives from running ahead of the ratchet movement by which said gear is actuated.

The warp is supported, at a point immediately preceding the shuttle mechanism, by a mandrel, 71, of cireular contour conforming to the inner diameter4 of the fabric to un Yao be woven, said mandrel being supported upon a bracket, 72, projecting from the framework 1, and correspondingly a mandrel, 73, is mounted upon a bracket, 74, and is operatively located, at a point immediately beyond the shuttle mechanism, to support the woven fabric. Operatively located, respectively with relation to these fixed mandrels, are clamping bands, 75-76, of corresponding circular contour, the band 75 of the mandrel 71 being adapted `to receive the spread ofthe warp threads (see Fig. 3) and clamp the same in proper relative position for-the weaving of the Woof, while the band 76 of the mandrel 73 is adapted to correspondingly clamp the' woven fabric, this clamping operation being maintained intermittently during the operation of the shuttle mechanism and the weaving `of the Woof. The clamp 75 is held under spring tension, to effect proper tension on the warp threads during the process of weaving, and the clamp is adapted to be automatically released against tlie tension of the spring to` permit the passage of the warp in the successivestep movements of the reel 3. In the preferred construction for effecting the operation just described, the clamp is di-- vided into two approximately semi-circular sections by a hinge joint, as at 77, one .of said sections having its free end in substantially fixed yrelation to the bracket 72 and the free end of the other section being pivotally connected toa' rod, 78, slidably mounted l in said bracket. Said rod 78 carries a laterj ally-projecting pin 79, to which'is connected a governing coiled spring, 80, extending from a fixed part of the framework 1, the action of which springr is to draw the clamp 7 5to normal clamping position withrelaj tion to the mandrel 71 (see Fig.'6). The pivotal connection between the rod 78 and the section of the clamp 75 is preferably detachable, the pivot being for this purpose constituted by a removable pin, 81, whereby the clamp can be disconnected from the rod 78 and lifted o ff the warp to enable the threading of the latter whendesired. The

automatic release of the clamp 75, topermit l the step movement of the ,warp underl the revoluble action of the reel, is effected by a mechanism which, in the preferred construe-,f

tion, comprises a bell-crank lever, 82, ful/ crumed, as at.l 83, upon the bracket 72, one

end of said lever being in operative connection with the slidable rod 7 8-by engagement with the projectingpin 79 thereof, .while to the other-end of said lever is pivotally connected a rod," 84, carrying a roller, 85, -engaging the periphery of the cam disk 66 upon the shaft 64. The movement of the mechanism, to elifect the release'of the clamp '75 against the tension of vthe spring 80 and; to permit the\`return of the clamp to normalv position under action of said spring, is suitinsegne said rod, the rod 84 whereby the bell-crank,

lever 82 of the governing mechanism of the clamp 75 is operated being extended (as/indicated at 86, Fig. 6) to a pivotal connection with the bell-cranklever of the mechanism governing the clamp 76, whereby the action of the cam disk 66 for the'release yof the warp'clamp 75 is simultaneously@'communicated to the clamp 76 for the actionthereof to release the woven fabric coincident with the step movement of the reel 3.

The shuttle mechanism is arranged intermediately with relation to the mandrels 71 and 73, and comprises a bracket, 87, projecting from the framework 1 and extending up within the path of movement of the woven fabric, said bracket carrying at its upper end a suitably journaled stud shaft, 88, arranged in the plane of the line of movement of the woven fabric and axially with rela'- tion to the segmental transverse contour thereof (see Figs. 1 and`2). Said stud shaft 88 carries a bevel gear, 89, meshing with a bevel gear, 90, carried at the upper end of a universal-joint shaft, 91, suitably journaled, as at 92, in a bracket projecting from the framework, and carrying at its lower end a pinion, 93., engaged by a rack bar, 94, moving in a suitable guide, 95, carried by the framework 1. Said rack bar 94; extends t of a magnetic shoe, 99, carried upon an arm, 100, fixed tothe end of said stud shaft oppo-I site the bevel gear 89 and projecting laterally with respect to the shaft, whereby in the oscillating movement of the shaft the` magneticshoetravels in reverse movements in a circular pathl corresponding to the circular `transverse contour of the fabric to be woven. The arm carrying the magnetic shoe is preferably of telescopic or adjustablefconstruction, to effect the operation of the magnet in proper relation to the fabric mass which is being woven` and in equi-distant-y relation to the inner transverse curvature of the fabric mass.

r weaving thistype of fabric, for instance, a

tubular endless fabric to conform to the normal contour of the body fabric for the lcarcass or casing of pneumatic wheel tires for automobiles or the like, the fabric is left `open at the inner side of its tubular transverse contour, where the edges are formed for `the engagement of the t1re casing with the clencher wheel rims, and that thiscon, tinuous ,opening accommodates the portions of the shuttle-operating mechanism l .which project within the fabric mass and also permits the operation of the rings 26 and 29`as hereinbefore described.4 In the preferred construction7 the bracket 87 car- 'Y ries receptacles, as at 101-101, respectively fat the termini of the reverse movements 'of the shuttles, for the reception of the shuttles at the end of their movements for weaving thelwoof threads (see Fig. 7). In Fig. 10, I have illustrated one type of construction for the adjustable relation of the magnetic shoe 99 to its carrying arm 100, the magnet being in this construction provided with an extension, 102, received by the arm` 100 and securedA in adjusted position by means of a set screw, 103.

In my present improvements, the purpose and operative function of the magnetic shoe 99 is to control the movement of the shuttle and effect its travel in the proper path of the reverse movements to lay the Woof threads through the sheds as formed by the heddles.

' tures controlled and moved by the magnet 99 in the reciprocating operation of the latter,Il by means of the mechanism as hereinbefore described, whereby the shuttles are carried tllirough the shed formed by the movement of the heddles in the usual manner of weaving with warp and4 Woof or filling threads. The shuttles, as shown at 104, may be in the main of any usual or adapted construction operating in the usual' manner to carry and feed the Woof or filling threads.

A batten mechanism is provided to properly close in or pack in position the Woof threads and enable the laying of the same in lines radiating from the axis of the reel. Said batten, as shown at 105, carries reeds,

` 106, and is operative within the fabric mass 'at a point immediately preceding the shuttle mechanism, and the batten with its reeds is carried by a downwardly-projecting arm, 107, connected at itsflower end with a hub, 108, which is loosely mounted on theextended hub 7 of the gear Wheel 8. Said arm 107 is of suitable angularcontour to properly` span the space between the batten 105 and the hub 108, and at a point intermediate of its ends it is pivotally connected, as at 109, with a rod or yoke 110, the outer end of which has a slotted bearing, vas at 111, upon the shaft 19 which carries the cam disk 18. Said rod 110 carries a roller, 112, engaging the peripher of the cam disk 18', whereby theirod will e reciprocated under action of the cam and impart an oscillating movement to the batten' to effect the action of the reeds to properly pack the Woof threads. In this oscillating movement the arm 107 which carries the batten has a bearing on its hub 108 which in turn bears upon the extended yhub 7 of the gear wheel 8. The operation of the batten mechanism is suitably timed with re- Sii lation to the action of theother general' mechanism, and is properly adjusted to the number of plies which are to be comprised in the woven fabric and the interweaving of the Woof threads to connect the plies in 'a unitary homogeneous woven fabric. For instance, under the four ply conditions as indicated in Fig. 10, the Woof threads are packed into position by the reeds of the batten after each cycle of movements of the shuttle to make the four ply connections of the Woof thread. Under the circular conditions of weaving, as indicated, in packing the Woof threads there will be, say, 25% more open space between the threads at the outer peripheral portion of'the fabric than atv the inner portion, there being approximately 25% difference in the circumference of the outer and inner diameters, whereby there is .produced a stronger rivet at the outer peripheral portion than on the sides, there being a gradual'decrease in the number of threads to the in'ch on the radial plane from the axis.

The heddle construction may be of any adapted type operative in substantially the usual manner to enable the laying by the shuttle of the Woof threads through the sheds as formed by the heddles. I have herein i1lustrated-a heddle mechanism, in its coperative relation `to the action of the shuttle mechanism and as adapted tothe operative action of the general mechanism of my improved loom. In this preferred Aconstruction of the heddle mechanism, the

are heldv in proper alinement at an angle of approximately 90 to each warp thread and the warp threads are laid to the desired tubular contour of the fabric. In the illustration as shown in Figs 10 and 8, there are eight sets of heddle rods, as adapted for the weaving of the fabric in a unitary homogeneous mass constituted by four4 directly connected plies. The heddles are actuated in their up and down movement, to form the shed through which the shuttle passes, by means of segmental cam rails,

v of heddle rods, there being four such cam als 117, whichare concentrically arranged with relation to the segmental frame 116 and are rovided in sets at opposite sides of the set rails in each side set, as shown iny Figs. 8

and 1. Thus, a cam vrail is provided for each heddle rod of the set of e1ght,\and the inclined surface, as at 118, of the rail enages fingers, as at 119, projecting laterally at the top ends of the heddle rods, whereby under the lateral movement of said cam rails an upward and downward movement will be imparted to the heddle rods. The

lateral movement of the cam rails is edected by cam disks, 120, carried by a shaft, 121, suitably journaled in the framework 1.

cam disk, as at 120, is provided for each` cam rail 117, and these cam disks respectively have an operative connection with their respective cam rails by Ineansof a connecting rod oryoke, 122, having a slotted end, 123, embracing the shaft 121 and forming a guide bearing thereon, said rod also carrying a roller, as at 1211, engaging the periphery ofthe cam'disk, 120, and being pivotallyconnected,`as at 125, to one end `of a lever, 126, the other end of which has a pivotal connection, as at 127, with a rod, 128, slidably mounted in lateral relation to the cam rail 117 and carrying the same in the reciprocal movement of said'rod. The

levers 126 are suitably fulcrumed, as at 129,

and the slidable rods 128 have their bearings, as at 130, in a supplementary framework, as at 131, mounted upon the main framework 1. It will be understood that the operation of the cams 120 and the general mechanism for actuating the cam rails 117 in their lateral movement to operate the heddle rods 115, is suitably timed with relation to the operation of the other parts of the general loom mechanism.

The various shafts as hereinbefore described, carrying the cam mechanisms and other operative elements, are in operative connection by means of a train of gears, 132,

as indicated in Figs. 1 and 2, whereby the movement of the main drive shaft is communicated to cause the simultaneous movement of the various shafts as comprised in the general loom mechanism, and that said shaft connections are so geared that the operationl of the various shafts and the mechanisms structions being reserved for /a separate/appt@ plication for patent.

The operation and advantages of my improved loom mechanism will be readily understood by vthose skilled in the art to which the invention appertains. The step move-- ment of the reel 3 gives the necessary travel to the warp threads after each movement or cycle of movements of the shuttle to Weavethe Woof threads. For instance, in -producing an endless tubular fabric of a single ply type, `the mechanism will be timed to advance the woof threads after each movementAll of the shuttle in the segment of thetubular fabric, whereas in weaving such fabric with multiple plies, as indicated in Fig. 10, the step movement of the reel to advance the warp threads will be-after the shuttle has completed the cycle of movements inthe segment of the tubular fabric necessary to lay a single woof strand through the warp threads of each of the multiple plies.

It will be understood that my improved loom mechanism is adapted for weaving; endless tubular fabrics in either single ply or multiple lies, and for weaving the otally-mounted peripheral means for carry plies in separate condition or with-therespective plies interwoven to produce a unitary homogeneous fabric mass, and also that the general features of improvement are adapted for effective and advantageous employment in looms adapted for the weav ing of various other types of fabric. For instance, the feature of the magnetic control of the shuttle action, and other features as comprised in the improved mechanism, may be employed in looms of various types for weaving either flat or tubular fabrics.

I do not desire to be understood as limiting myself to the detail construction and arrangement of parts as herein shown and described, as it is manifest that variations and modifications therein may be resorted to, in the adaptation of my invention to varying conditions of use, without departing `from the spirit and scope of my invention and improvements. I'therefore reserve the mechanism comprising means proj ective peripherally for carrying the warp, and means from engagement with the warp as the latter passes up to the shuttle mechanism.,
